California Tornadoes

Did you know that portions of California experience tornado frequencies comparable to those observed in Oklahoma and Kansas?

Discovering the evidence for this and investigating the patterns responsible for these tornadoes form the bases for my research focus. Two classes, one a non-majors offering and one a majors offering, have spun off of this research area, as well as a number of MS Theses students and refereed publications.
